Abstract
Linear roller bearing assemblies can include a hub, a collar around the hub and roller bearing sub-assemblies disposed in a radial pattern around the hub. The roller bearing sub-assemblies can guide linear movement of the hub relative to the collar along a selected direction. Each roller bearing sub-assembly can include a roller and straps wrapped partially around the roller. Each strap is connected to at least one of the hub and the collar. And at least one of the straps can be connected to the roller while at least one of the straps can be circumferentially free of the roller. The hub and collar are moveable relative to each other along the selected direction for a distance that is approximately half of a circumference of the roller. Methods of forming linear roller bearing assemblies are also disclosed, as are multi-cylinder Stirling engines and a thermal energy recovery system.
